Kaolin grinding production process

November.14,2024

The following is a method for preparing kaolin powder

Crushing

The large pieces of kaolin powder are crushed by a crusher to a feed fineness that can enter the mill (15mm-50mm).

Grinding

The crushed small pieces of kaolin powder are sent to the silo by an elevator, and then sent to the grinding chamber of the mill for grinding evenly and quantitatively by a vibrating feeder.

Traditional ball mills and Raymond mills have low grinding efficiency, high energy consumption, and low output. Guilin Hongcheng HLMX series ultra-fine vertical mills integrate multiple functions such as crushing, drying, grinding, and grading and conveying. It has complete functions, perfect performance, high grinding efficiency, low operating costs, low metal content, and high product quality, which is conducive to the next step of calcination and deep processing, and the fineness of the finished product is guaranteed.

The ground kaolin ore powder is graded by the separator of the mill. The unqualified finished products are separated by the separator and returned to the main machine for re-grinding.

Powder collection

The finished products that meet the fineness are collected in the dust collector along with the air flow through the pipeline. The collected finished products are sent to the finished product silo by the conveying device through the discharge port, which meets the national environmental protection emission standards.
